1.Water is more efficent than air in transferring heat. True, unless that water is also hot. Cooling 230 degree oil with 210 degree water may not be as effective as cooling 230 degree oil with 80 degree air. Granted, since water is much more effective the temperature difference can be smaller for the same effect, but there's a point where it is less effective. Again, you MUST have an adequate water cooling system for it to work.
2.The whole system will weight less than any oil to air system, that gives you equal cooling. Not sure if you have weighed both systems but the air/oil cooling system vs. the water/oil cooling system we used on the car I race weighed about the same. Totally different cars though.
3.You have more options in location, leaving the front open for intercooler/radiator. Agreed. Plus you can put the weight in a more ideal place.
4. With mulitple large oil to air, I have a feeling that you are taxing the factory oil pump. I would rather have the pressure/volume to the engine.Being the most oil to water are about a 1/3 in overall size to the comparable oil to air, less stress on oil pump. Agreed.

The situation with the 135i is not comparable for obvious reasons, installer/chassis/equipment plus BMW cooling system is horrendous. If there's one car that I would say is worse than the BMW cooling system its the 370Z.

Bonnani, good info but remember you are cooling the oil with the output of the radiator. On average output temps are around 165-170 not 210 to 230 so this will help keep oil temps in check.

A little off topic but I had '08 x5 in the shop last week, for an overheat conditio, now that cooling system is horrible!! The electric wp went bad @ 52k miles.

True, but also remember that the oil will be heating the water a bit too so it will be hotter than usual at the point it goes into the radiator in the first place. Long story short, you NEED a proper water cooling system for a Laminova cooler to be effective. Simple as that.

Do you have any reason to believe the stock radiator isnt enough? No matter what I do I cant get the temp past the halfway dot in my car, even with the sc.

I got mine all the way to the right in one track session on a hot day, it was my bad for not noticing right away. This was mostly due to blocking air to the radiator with my oil cooling setup. Since adjusting that I can only make it move 2 dots right of center, and half a lap of cool down brings it right back to left of center. By the time I get to the pits and plug in an ODBII reader it says 195F.

Is this on the track or the street? I began to see signs of coolant temp issues on my 370Z when I had the AE Performance oil cooler installed. Since it blocked a decent portion of the front bumper opening, after 20 or so minutes of track driving the water temp gauge was reading about 3/4 hot. I can't imagine the FMIC for the supercharger kit or the supercharger kit itself will make it any better. Not to mention the oil/water heat exchanger heating/cooling both the oil and water at the same time. On the street, not a problem, but Travis' car does not see the street. Now I could very well be wrong, and it would be nice if I am but if he wants to be running 20-30 minutes at a time without issues, I see a big radiator in his near future. The good news is that no matter what, there's going to be a fix and the fact that Travis' car is a track only machine opens up a world of fun possibilities for that fix.

Travis's car has a very large aftermarket radiator and no condensor in it to obstruct the air flow, temps won't be an issue. Without this, Bonnani your are correct he would need upgrading.

Problem solved!

Hopefully. If not, then I say custom front radiator support that allows for v-mount radiator/intercooler.
